Title: LIGHT-EMITTING DIODE (LED) DRIVING DEVICE AND LED LIGHTING DEVICE CONTAINING THE SAME
Abstract:
The present disclosure provides a light-emitting diode (LED) driving device, including a control unit and a power unit integrated on a packaging substrate to form an integrated circuit (IC). The control unit is electrically connected to the power unit for controlling the power unit to convert an AC current to a DC current for an LED load to emit light. The control unit is configured to generate a control signal with a lowest working frequency higher than 250 KHz.
